I am a new Rx-8 owner and, like most of us, have at least known that we did not know so we are here. I just want to put this straight forward, before and after with pic + OBD ii reports out there for the rest of the new guys. If you have yet to check your MAF sensor, DO IT NOW! I almost killed my 8 because I did not do a thorough check up immediately following the purchase, it caused a world of trouble! In four days my 8 was stuttering idle, could barely reverse up my inclined driveway, was running way to rich and sometimes would not make it to red line!
It is important to note that following this I reset the NVRAM to allow the Fuel Trim and O2 sensors to re calibrate.
Turn key on and within 8 seconds stomp the brake 20 times (success indicated by the temp gauge jumping toward H in some models)
Then turn key off, turn key on and in order to get the DTC light to stop blinking you need to turn your wheels all the way to the right and then all the way to the left. It should be off now.
The first attachment is a report generated by my ACTRON code scanner, even if you do not know how to read it, look at the fuel trim numbers, MAF numbers and the O2 sensor readings, heck it messed with darn near every sensor in the car. Just compare the two, this is just for those who need visual aids.
I used hydrogen peroxide to clean the MAF, it took about 20 minutes total. Notice that the dirty MAF pic is covered in what appears to be oil. I also checked the air intake (I already picked up a new air filter and through out the K and N).
I have seen a lot of comments from new guys asking what stuff looks like and what a OBD ii report reads like, here is before and after reports.
I hope this helps someone, I pretty much was up all night making sure I had my 8 running and now I have to go to work.
